Universality: Exclusivity alone does not create value because value is not automatically generated by monopolizing something that isn’t worthwhile. For a monopoly to effectively build value, the monopoly object must be scarce and in limited supply. Conversely, universality also creates value. Scarcity relates to the concept of universality as a correspondence, and the value of universality is also affected by the limitations imposed by scarcity. Nothing has absolute value; all values are merely relative. - Joseph’s “just my thoughts”
For the security of the Internet service, we have been asked by the Internet service companies to set the password combined by more than 8 or 10 "uppercase letter+lowercase letter+number+special character". But it was obviously of no use. This security guideline was recommended by Bill Burr who worked at NIST in the USA, he suggested this way in his report. Furthermore, the user was required to change the initial password set regularly. Despite this measure, the best way of security to protect users' accounts was the notification of the alarm for attempted hacking when the hacker tried. We have only tried to change the keys despite the simple method meanwhile. Today, the world has begun to comprehend that the security problem is not encryption or confidentiality, but simply cyber-dominion control and communication. - Joseph's "just my thoughts"
